Although the MiG-15 "Fagot" fighters were initially equipped with an AFA-IM camera as standard (> Link), it was nevertheless a real fighter, revealed during the Korean War. However, a directive of the Council of Ministers of April 1950 instructed Mikoyan's OKB-155 to develop a reconnaissance variant of the MiG-15
carrying an AFA-BA/40 camera (> Link 1 / > Link 2).
The aircraft chosen for this modification was a MiG-15bis, which was given the designation SR (Samolet Razvedchik - Reconnaissance Aircraft). The camera was mounted between the guns, between frames n°8a and 9, in the same place as the AFA-IM of the MiG-15. The MiG-15 and MiG-15bis "Fagot-B" had a similar armament with a 37mm N-37 cannon on the right side of the nose and two 23mm NR-23 cannons on the left side. However, since the AFA-BA/40 camera with a focal length of 400mm was larger than the AFA-IM, the inner NR-23 cannon was not mounted on the SR in order to make room for the camera. A new fairing extended behind NR-23 outboard cannon, providing the only way to identify a reconnaissance MiG-15bis without looking for the ventral hatch hiding the optics.
The aircraft also underwent other modifications to eliminate defects found on the MiG-15 such as fogging or frost; a chemical filter was fitted to treat stale air in the cockpit and the pressurization system was improved among other things. However, the tests conducted between August and September revealed many shortcomings such as insufficient photographic coverage, the absence of pivots on the camera (although this was not requested), and a malfunction of the air conditioning system. The aircraft nevertheless retained its performance and combat capabilities and was able to carry out tactical reconnaissance flights. In order to increase the range, new D4-50 hardpoints were fitted in the wings to carry drop tanks with an increased capacity of 600 liters fixed flush under the wings.
The MiG-21R "Fishbed-H" therefore succeeded the MiG-15Rbis within the 294.ORAP, which represented a major upheaval, both in terms of the aircraft itself and the reconnaissance means it was capable of carrying. The prototype of the MiG-21R, built like the MiG-15Rbis at the Gorky plant, was based on a MiG-21PF "Fishbed-D" interceptor airframe. The R-11F2-300 reactor of 3950 kgp dry (6120 with AB) was replaced by a R-11F2S-300 model with the capability to blow air above the flaps in order to further increase the lift when the latter were extended. Externally, the prototype resembled a MiG-21PFS with its short-chord vertical stabilizer and the braking parachute relocated to the base of the stabilizer. However, small cigar-shaped fairings housing the antennas of a SPO-3 "Sirena" radar warning receiver were mounted on the wingtips. It was inended that different reconnaissance containers could be mounted alternately under the ventral hardpoint. In order to compensate for the unavailability of the latter, which was the only one on which an additional fuel tank could be attached, two new "wet" hardpoints capable of receiving 490-liter PTB-490 drop tanks were added outboard the two existing wing pylons. The centrally mounted PVD-7 pitot tube above the engine air intake, which obstructed the pilot's downward view, was moved to the right. The first flight of the Ye-7R, as it was designated, took place in 1964.
- "D" model (Dnevnaya fotorazvedka - daytime photo reconnaissance). This container had a marked recess under its nose to allow forward photography.
It carried seven cameras, including six A-39 (> Link). A pair of the latter was housed behind
the front recess to cover the sector below the plane's flight axis.
The other four A-39 were located at the rear of the nacelle, also arranged in pairs, one covering the left sector and the other the right sector.
The seventh camera of the AShchAFA-5M type (> Link) designed to cover
strips of terrain (see the two rectangular holes in the photo above) was placed just behind the two forward-pointing A-39 cameras.
The area covered by the vertical cameras was 0.7 times the flight altitude, and twice that for the oblique cameras.
The SPO-3 complex, whose antennas were housed in the fairings at the wingtips, a magnetic tape recorder
Lira and an ASO-2I flare launcher system with two KDS-19 cassettes, each of which capable of firing 32 thermic or electromagnetic (chaff) flares, were located in the rear section of the nacelle.
- "N" model (Nochnaya fotorazvedka - night photo reconnaissance). This version dedicated to night reconnaissance carried a UA-47 camera
(> Link) with two lenses inclined 160° to the left and right.
Night photography was made possible by four KDF-38 cassettes containing a total of 152 FP-100 illumination flares, which occupied the space of almost a third of the nacelle.
An ASO-2I flare launcher system was located in the tail section. The "N" pod also included the Lira recorder and the SPO-3 complex.
- "R" model (Radiotekhnicheskaya razvedka - electronic reconnaissance). This container was easily recognizable by the large dielectric panels
of the SIGINT systems SRS-6 Romb-4A and SRS-7 Romb-4B (Rhombus) that adorned its sides. The electromagnetic signals captured by this radar detection/classification/location suite were recorded on magnetic wire. An A-39 camera remained mounted in the front, while an ASO-2I flare launcher system and an SPO-3 complex were located in the tail section.
The pilot used a control box fixed under the upper arch of the windshield (click on the drawing on the right), to control the various reconnaissance systems, the flare launchers or the radar warning receiver.
There were at least three versions of control box for the D, N and R containers. Thus, a good part of the aircraft always flew with the same type of container,
in line with the control box mounted on the aircraft.
The MiG-21R retained air-to-ground capabilities, being able to carry conventional UB-16-57UMP or UB-32 rocket launcher pods, 50 to 250 kg bombs, or S-24 rockets under the inboard hardpoints.
It could perform interception missions when armed with a pair of RS-2-US type IR-guided missiles also mounted under the inboard hardpoints. R-3S missiles could be placed under the inboard or outboard hardpoints. Sometimes, the antenna fairings of the SPO-3 were removed for these missions because they were unecessary, since the system's electronics were housed in the reconnaissance pods. The RP-21M radar of the MiG-21PFM was mounted in the nose.
Two-seater versions of the MiG-21 of course flew within the 294.ORAP, from the early MiG-21U model to the latest MiG-21UM version.
Fitters
In 1978, the 294.ORAP became the first of the twelve VVS units to receive the reconnaissance version of the Strij (Swallow) as the Su-17 were nicknamed (see section "3.3 Ground-Attack Aviation and Fighter-Bombers" for more information about the different versions of the Su-17 > Link).
These were Su-17M3 "Fitter-H" which coexisted for a time with the MiG-21R in two different squadrons - the third squadron was disbanded. In August 1981, the second squadron was in turn completely re-equipped with new Su-17M3 of the 64th series. In total, 30 aircraft equipped the regiment, namely 24 single-seater Su-17M3 and 6 two-seater Su-17UM3 in the mid-1980s.
A note should be made concerning the designations of the reconnaissance versions of the Su-17M3 and M4. While there was a manufacturer designation for the M4 recce version, namely S-54R, this was not the case for the Su-17M3, which remained S-52 in all cases. We can also see on the table above that the single-seaters were simply designated S-52 and the two-seaters S-52UM3. The Su-17M3 built from the 54th series onwards bore the designation S-52P and, like the Su-17M4, were capable, in addition to ordinary ground attack missions, of carrying out two specific missions. They were either reconnaissance with carrying specialized pods, or anti-radar missions (V'youga container, Kh-25MP, Kh-27PS and Kh-58U missiles). In practice, the aircraft of a unit dedicated to reconnaissance such as the 294.ORAP quite logically kept a fixed configuration. We will nevertheless designate the reconnaissance versions by the letter R at the end in order to avoid confusion.
- The KKR-1 model was equipped with an A-39 camera in the front (it was set to a vertical or oblique position up to 55° before the flight). It was used at low or medium altitudes up to 5000 meters. Next came a PA-1 panoramic camera equipped with rotating prisms for photographing strips of terrain to the left and right of the aircraft. The length of the photographed strip corresponded to ten times the flight altitude. Finally, a UA-47 camera
(> Link) with two lenses was intended for night photography. For this purpose, it was paired with four KDF-38 cassettes containing FP-100 illumination flares. These cassettes were mounted only when needed, otherwise their slots remained empty as can be seen in some of the photos illustrating this article or in the associated photo gallery. Panoramic and night photographs were not taken above 1200 meters altitude. The aft part initially housed a SIGINT SRS-9 Viraj system, later replaced by the SRS-13 Tangaj, whose dielectric panels were visible on the rear sides of the nacelles. The SRS-13 suite was intended for radar localization, classification and frequency identification. Thus equipped with the SRS-13, the container took the designation KKR-1T (for more information on this container, visit this > Link /
video detailing a KKR-1T from the LSK/LV > Link).
- The KKR-1/2 model retained the same cameras, but the aft part this time housed module n°2, which included an 8R Zima (Winter) thermal imaging complex and a 429T Chibis-B (Lapwing) television reconnaissance station. The TV and IR images were relayed to a ground station via a Trassa data link suite, the antennas of which were visible under the container. Module n°3, mounted in place of n°2, included a SRS-13 Tangaj SIGINT suite and a Shpil'-2M laser reconnaissance unit. In the latter case, the container designation became KKR-1T/2.
There was also a KKR-1M pod equipped with an AFA-42/100 camera (> Link) as well as Chibis-B and Zima systems. The AFA-42/100 camera with a focal length of 1000 mm, also used by the Long-Range Aviation on board the Tu-16R and Tu-22R, was specifically designed for long-range oblique photography from high altitudes.
The Su-17M4R used KKR-2A containers (cameras A-39 and AP-402, Aist-M TV and Zima IR systems), KKR-2T (SRS-13 Tangaj), KKR-2Sh (SLAR Shtik-2M), KKR-2P (Shpil'-2M) and KKR-2E (Efir-1M) - for the Aist-M, Shtik-2M and Efir-1M see > the 11.ORAP.
Many of the reconnaissance systems carried on board the Su-17M3R and M4R pods were later integrated into the Su-24MR. The 8R Zima infrared complex recorded thermal images on film and quite logically allowed night reconnaissance. A rectangular fairing oriented in the direction of flight located under the container betrayed its presence. The TARK 429T Chibis-B reconnaissance system mounted in front of it ensured the transmission of live images to a ground station mounted on a truck. However, a lower quality image was the price to pay. The Shpil'-2M laser worked with an illuminator and a photodetector. The images recorded on film were of better resolution than thermal images, but close to those on television. The illuminator function was not necessary during the day.
The 294.ORAP did not survive German reunification for very long, even earning the title of the first regiment of the 16.VA to evacuate the territory of the former GDR on the occasion of its final withdrawal in the spring of 1991. However, it should be mentioned that, unlike other departures of units of the 16.VA observed at the same time, the departure of the 294.ORAP did not take place within the framework of of the negotiated general withdrawal of Soviet forces from Germany, but by virtue of the so-called CFE (Conventional Forces in Europe) agreements, relating to the reduction of conventional forces in Europe
(2).
On 21 May, the regiment definitively left Allstedt for Jekabpils in Latvia where the 886.ORAP equipped with Su-17M4R was stationed.
But, still to remain in compliance with the CFE agreements, a squadron of the 294.ORAP was quickly transferred to Domna in the Transbaikalia district,
where its Su-17M3R became a squadron of the local 125.ORAP aligning two other squadrons equipped with Su-24MR. These Su-17M3R were withdrawn from service in 1995 and to the storage base of Step'.
The equipment and personnel of the other squadron of the 294.ORAP were distributed between Transcaucasia in Vaziani in order to reinforce the 313.ORAP then equipped with Su-17M4R and Uzbekistan at Karshi-Khanabad where the 87.ORAP was based with Su-17M3R.

There are several interpretations of the designation of the MiG-15bis reconnaissance aircraft: MiG-15bisR, MiG-15R-bis and MiG-15Rbis. We will
stick to the latter designation, since it is the one that appears on the technical document at the top of this page.

The CFE agreements were signed on November 19, 1990 in Paris, on the occasion of the Conference on Security and Cooperation in Europe
(CSCE, now an organisation abbreviated to OSCE), by 22 countries of the Atlantic Alliance and the Warsaw Pact.
